So now facebooks really wants your phone number, so glad I got rid of whatsapp ages ago
If you're interested in have private communications with people, you should look into my XMPP thread. There are mobile apps that support encryption. It's right here.
I would love to use this, but I'm the only one who really cares about tin foil hats and privacy and I haven't the effort to get people to use this.. le sigh
I opted out of that feature...
There was a box you could uncheck.
I wonder if it's something that I'm going to have to look for with every update now - hopefully only with updated TOS though. The good news is at least your messages are encrypted and not being logged -- they just want your phone number, username, and statuses I believe........ for now. Tomorrow - your soul.
3 years facebook free and proud of it.
